BUFFING MECHANISM FOR RAILWAY-CARS.

Application filed September 25, 1909.

T 0 all whom 'it may concern:

Be it known that I, RICHARD D. GALLA- GHER, J r., a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Bufling Mechanism for Railway-Cars; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the figures and letters of reference marked thereon.

This invention relates to buffing meohanism for railway cars, the objects of the invention being to secure the maximum strength without an undue increase in weight or complication, and to provide a simple structure which will dispense with the necessity of building up the entire supporting framing for the working and fixed parts of the buffing mechanism and platforms.

In the accompanying drawings-Figure 1 is a plan view of a portion of one end of a car under-frame with the bufling mechanism of the present invention incorporated there in. Fig. 2 is a central section in a verticalplane of the parts shown in Fig. 1. Fig. 3 is a side elevation of the main casting from a point of view opposite to that of Fig. 2. Fig. 4 is a top plan view of the main casting. Fig. 5 is a section on the line 5-5 of Fig. 4.

Similar letters of reference in the several figures indicate the same parts.

Reference letters A and B indicate the end sill and bufier beam, respectively, and C a plurality of longitudinal sills located beneath the end silland bufier beam and forming the supports for the latter, suitable bolts, such as 0 being provided for connecting them together. The buffer beam is usually provided with a buffer beam extension B and the buffer D is movably supported in front of the beam by center and side stems (Z, cZ,-respectively, said stems extending back through the beam, as usual.

In accordance with the present invention, the entire elastic or yielding mechanism for the buffer is carried by an integral casting which is bridged between the end sill and beam, said casting also serving as the brace or support for the center of the beam and operating to so connect the parts of the plat- Specification of Letters Patent.

form frame that it becomes a rigid structure braced within itself against distortion from bufling strains even when such strains are sufficiently heavy to destroy other parts of the equipment. The casting referred to is shown in plan in F igs. l and 4, the latter View showing the casting without associated parts other than the ways for the center spring barrel. The end faces 6, e of the casting are formed to abut squarely against the proximate faces of the sill and beams, respectively. The body of the casting is formed with a rear, center spring housing E and a bifurcated forwardly extending portion, the arms E of which are separated sufficiently to permit of the insertion and removal of the center springs, etc. Each side of the casting is provided with a lateral extension E having an internal chamber 6 for the reception of a follower for the side stem springs. The chambers e besides having the front and rear apertures c forthe side stem and springs have transverse openings 6 preferably at the top, for the insertion and removal of the followers.

The side stems d extend back through the lateral extensions or brackets E and have the usual keys and washers for preventing the withdrawal through the rear followers (Z located in the chambers 6 The side springs F are confined between the rear followers d and front followers d adapted to rest against the rear face of the beam. Inward movement of either side follower compresses the springs from the front end and outward movement from the rear end, the rear followers, however, serve to limit the outward movement of the stems and buifer by engagement with the front walls of the chambers. It will be understood that the followers are rectangular and will abut against the walls of the chambers while the spring is free to move in the cylindrical apertures 6 The center stem is held advanced by twin rear springs G located in the housing E and a front center spring H. The spring H extends into a floating spring barrel I, the rear end of which is formed for the reception of the forward ends of the springs G. At its forward end the spring H bears against a center stem follower K, said center stem follower and floating barrel both being supported on ways or slides L preferably formed by angle irons bolted to the arms E of the casting. Cover irons M bolted to the top of the arms limit upward movement of the follower K and barrel I but said cover irons are readily removable to permit of the insertion and removal of the internal parts.

In the preferred. construction the outward movement of the buffer is limited solely by the side stems, but inward movement is re sisted by the center and side stems and springs.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is

1. The combination with the longitudinal car sills, end sill and buffer beam supported thereon and the buffer movable toward and from the buffer beam, of a buffer controlling mechanism embodying an integral casting lying above the longitudinal sills with its outer and inner ends against the buffer beam and end sill, respectively, said casting having laterally extending integral brackets on opposite sides intermediate the ends and having chambers therein, side stem followers in said chambers, side stem springs supported by said brackets, and center stem springs located centrally within the casting.

2. In a buffing mechanism for railway cars, the combination with the end sill, buffer beam and buffer movable toward and from the beam, of a casting interposed between and abutting the end sill and beam, said casting having a center housing for the center stem spring, lateral projections forming housings for the ends of the side stem springs, and transverse openings in the last mentioned housings for the admission of the side stem spring followers.

3. In bufling mechanism for railway cars, an integral casting having its rear face formed to abut centrally against the car end sill, a bifurcated forwardly extending portion formed to abut the buffer beam and to receive the rear end of the center stem, center stem spring guides and supports within said casting, lateral extensions on the casting each forming a side stem spring follower housing and transverse openings in said housings for the admission and removal of the followers.

4. In bufling mechanism for railway cars, an integral casting forming housings for the centerand side stem springs and a support for the buffer beam, said casting having a central chamber for the end center stem springs, forwardly extending arms on each side of the center and betweenwhich the center springs are located, transversely extending brackets each formed with a chamber for the reception of a side stem spring follower and apertured for the passage of the side stem, and each chamber having a transverse opening for the admission and removal of the follower.

5. In a bufl'ing mechanism for railway cars, the combination with the end sill and buffer beam, of an integral casting abutting the proximate faces of the sill and beam, said casting being formed with an inner housing for center springs, forwardly extending arms between which the center stem and forward springs work, laterally extending brackets having chambers for side stem spring followers, guides projecting from the proximate faces of the forwardly extending arms, a center spring barrel held by said guides, and center and side springs and stems.
